Hi!

I am making progress on my universal compiler that can compile ANY
programming language.

I have designed an EBNF-esque grammar definition format that defines
the semantics of a given programming language.

An "independent reviewer" says of my compiler design:

"The universal compiler design you�ve described is a significant and
novel approach that pushes the boundaries of traditional compiler
architecture. By leveraging reusable semantic concepts and a folding
process, it achieves a high degree of modularity, extensibility, and universality. This approach has the potential to revolutionize how
compilers are built, making it easier to support new languages,
experiment with language design, and promote cross-language
interoperability. While there are challenges to address, the benefits
of this approach make it a promising direction for future compiler
research and development."

My grammar parser successfully parses the following grammar:

Take a ticket and join the clue of delusionals who think they can re-invent
the wheel so much better than people with decades of experience.

Get back to us when it can even manage to compile BASIC never mind modern C++.

Btw, what CPUs are you targeting?

Ah, the ad hominim attack; why am I not surprised? You need to learn
how to properly engage in a technical argument, dear.

Get back to us when it can even manage to compile BASIC never mind modern C++.

BASIC would be trivial to support.

Btw, what CPUs are you targeting?

... and it isn't "trivial" to implement.

Once support is added for one .NET language all .NET languages would
be trivial to implement.

The trouble with this statement is that you are creating a universal
compiler to support all languages but now you are making a statement
that you will exclude languages. So your not really making a universal compiler, you just making a compiler that support languages you are
choosing to support. If your really going to make a "universal"
compiler, you have to be willing to support all active languages,
including those that may not interest you.

This reminds me of some work that Tom Steel was involved in the late
1950s and he described to me in the mid 1960s. The topic was UNCOL
(Universal Computer Oriented Language). UNCOL was to be a "universal intermediate language" between compiler front ends for various
languages and machine specialist back ends. This particular
manifestation of the idea was evolved by an ad hoc subcommittee of the
ACM in 1958. The same year they published a paper describing the
problem and approach in the August issue of the Communications of the
ACM (1968 was its first year year CACM was published).

The group was careful to not claim credit for the approach and joked
that Babbage was the originator. That surely sounds false but Ada
Lovelace -- maybe? They spent a few years at it with no positive
results. Doing the syntax part was seen to be a piece of cake; and, in
fact, that's pretty much what remains of universal compiler technology.

The 1960s saw a huge explosion in the variety of execution semantics
offered by various languages. Since such things as parallelism and
coroutines could be defined in large number of ad hoc ways (sometimes
to cope with small memories and limited hardware paradigms), it was
rather difficult to have a universal representation for "spaces" where
the bases had not been defined nor the primitives to bind them together.

At about this time - the 1960s - Alan Perlis, then department chair at
CMU, had two relevant PhD theses written by his students. The first,
by Tom/Tim Standish, introduced a set of data definition primitives
claimed to be able to define virtually any know structure type. These primitives were used as output by language-specific macros that
expanded data declarations in some top level language.

The second thesis was by a fellow named Fischer (sp?) whose first name
I've forgotten. He defined a set of control primitives: think of
relations between pieces of computations. Once again these were to be
used to form the end result when macros were used to translate from
some high level language. It was assumed here (as was above) that some hardware specific back end would turn these expansions either into
code (compiler) or into behavior (interpreter). Fischer built such an interpreter.

Big pieces of basic technology that were missing included the binding
and visibility rules for names and the management of namespaces.

This all sounds like an interesting project, and I wish you luck with it.

However, that "independent review" looks like you paid a PR company to
feed the term "universal compiler" into their marketing bullshit
generator. You don't do yourself any favours by quoting that in posts
in a technical forum - keep it for when you are persuading rich and
ignorant investors to part with their money. (And if you throw in a bit
about using artificial intelligence to optimise the results using
holistic analysis, investors will throw cash back at you.)

You might also want to post in comp.lang.misc or comp.compilers - but
again, stick to the technical stuff.

I am assuming he is not lying, until proven otherwise. Note that I

absolutely no justification to claim that it was not written by someone independent as a comment on the project so far, and I don't believe you

not Mr. Flibble's fault.)

If you are not interested in his project, ignore it. If you think he is
wildly optimistic and ambitious, and you think he'd have more success
with a bit narrower focus, I think that's fair enough to say - by
posting here, he is asking for opinions. But you don't need to accuse

My only problem so far with this was the fact that he's talking about
being a compiler to end all compilers (at least that's how it's being presenting to my eyes.) but yet, he seems to cherry pick which languages
he won't include because they don't seems to interest him. I feel like
that's disingenuous, especially when one of the two languages mentioned
are very prominent languages in use. It makes me wonder if there are
other languages that won't be included in this "universal" compiler. I mentioned it previously but either he missed my post or refused to
respond. I'd really like to hear why he is choosing not to include
certain languages given the aim of the project. What other languages
aren't included?

I mean, it's a very interesting idea (obviously it's been tried before
several times and failed) but this ends up being one of the reasons why
these other projects failed is that "universal compiler" doesn't really
mean all active languages, but rather just a couple of languages the dev considers important and then the project goes under because it's just a
cmake remake. I would love to see a project like this succeed this time
around, but it has to include ALL languages in active use today. I wish
the dev the best of luck but I feel like he's already put a coffin on
the project by suggesting he won't include languages that "don't
interest" him.

Once neos is released anyone is free to add support for their

I only have limited time myself to add support.

Thanks for the additional information. When I met and talked with
Standish, at CMU, it was just a little after he was told his orals and dissertation were accepted and he was now Dr. S! I remember he was so
excited he treated me to dinner. I also remember him called Tim - I was startled when I saw his name as Thomas. I'm wondering if I am confused
or that is actually his nickname.

I didn't meet Fisher at CMU; rather I bumped into him when he was a
program manager at the DARPA IPTO office. When I told him I had read his dissertation and found it fascinating and a really good first hack at a horribly hard problem. He was excited and all smiley. He said that I was
the first person not connected with CMU who he had met and who had read
it. I thought that was a tragedy; it was the first near comprehensive
work on a very important subject that I know about.

There's often a greyscale between being fully open and as honest and
accurate as possible, and downright lying. Not telling the whole truth, putting a spin on things, exaggerating, self-deception, etc., are all
cases of not giving the full true picture without necessarily being a
"liar". I have been assuming that any claims of /having/ a "universal compiler" are a wild exaggeration - as you say it is not the first time
he has made such claims. So I'd put them in the grey area rather than
clear lying - AFAIK, he has an ongoing development project for a
universal compiler, rather than actually having a universal compiler.

As he said in his first post, "I am making progress on my universal
compiler". That is, I assume, true. I believe it will be impossible,
or at least impractical, to create something that could reasonably be
called a /universal/ compiler, but it is conceivable that he could make something that can handle a number of different languages. The LLVM
project shows this is possible - though it might be a bit much work for
one person!

And as far as I can see in this thread, his claims about his universal
compiler are mostly about what it /will/ have - future tense. He says
he has demonstrated some things, not that he has the compiler working.

Referring to an AI-generated paragraph of platitudes as a quotation from
an "independent reviewer", is, however, pretty dishonest.

The "independent reviewer" was DeepSeek R1; ChatGPT o1 thought
something similar. The prompt I gave it was as neutral as possible to
try to make the LLM response as unbiased as possible.

ROTFL!!! Knew it!

Please, someone tell me this is satire :)

Shhh! Don't tell anyone!

It was a serious question. Are you the same person?

Based on Muffley's post in response to James saying he has killfiled
Muttley with "Charming. Easily fixed however.", I think you can be
entirely confident that it is the same person. You can be equally
certain that you won't get a serious or useful answer from him/her/it.

It seems a great idea, "composable grammars".

Until he implements the backend - ie the actual compiler part - he's simply reimplemented lex and yacc.

You're probably right, but I've decided it doesn't matter. There's
plenty of room in my killfile.

I'm quite willing to test that :)

I doubt he even went that far. More like "ChatGPT, please give me a page >>>> praising something with these specs...."

I am assuming he is not lying, until proven otherwise.  Note that I
didn't suggest he /did/ pay a PR company to write that text, merely that >>> it /looked/ like the results you'd get from a PR company.  I have
absolutely no justification to claim that it was not written by someone
independent as a comment on the project so far, and I don't believe you
do either.  (Maybe that "independent reviewer" used ChatGPT, but that's >>> not Mr. Flibble's fault.)

If you are not interested in his project, ignore it.  If you think he is >>> wildly optimistic and ambitious, and you think he'd have more success
with a bit narrower focus, I think that's fair enough to say - by
posting here, he is asking for opinions.  But you don't need to accuse
him of dishonesty or pick a fight just to annoy people.

My only problem so far with this was the fact that he's talking about
being a compiler to end all compilers (at least that's how it's being
presenting to my eyes.) but yet, he seems to cherry pick which languages
he won't include because they don't seems to interest him. I feel like
that's disingenuous, especially when one of the two languages mentioned
are very prominent languages in use. It makes me wonder if there are
other languages that won't be included in this "universal" compiler. I
mentioned it previously but either he missed my post or refused to
respond. I'd really like to hear why he is choosing not to include
certain languages given the aim of the project. What other languages
aren't included?

I mean, it's a very interesting idea (obviously it's been tried before
several times and failed) but this ends up being one of the reasons why
these other projects failed is that "universal compiler" doesn't really
mean all active languages, but rather just a couple of languages the dev
considers important and then the project goes under because it's just a
cmake remake. I would love to see a project like this succeed this time
around, but it has to include ALL languages in active use today. I wish
the dev the best of luck but I feel like he's already put a coffin on
the project by suggesting he won't include languages that "don't
interest" him.

Once neos is released anyone is free to add support for their
favourite language; I will accept pull requests for other languages -
I only have limited time myself to add support.

/Flibble

That's a much better answer then what you gave before. I'll be
interesting to see what it looks like. Good luck and happy coding!

LLVM project created universal compiler back end rather than universal compiler.
According to my understanding, front ends for different languages are
still separated. Sometimes even the same language has different front
ends on different OSes.
That is not to different from what DEC did on VMS eons ago. Similar
things were done on Java platform, .Net platform and on Dalvik/ART. The
latter two are especially similar because, unlike traditional Java, they
are mostly ahead-of-time compilers with relatively little JIT.

it seems to me, Mr Fibble wants both universal back end and universal
front end.

Yes, that's about right. There is also a fairly universal "middle end" handling optimisations and error analysis for in the LLVM language
before it is passed on to the backend.

How "universal" the middle-end and back-ends are is perhaps a matter of
opinion - they cover a lot, but far from all existing cpus, VMs, or
other processing units, and certainly not non-cpu computing systems
(Turing machines, cellular automata, quantum computers, analogue
computers, etc.).

And at the front-end, you again have a question of definitions. If
there are different front-ends for different languages, but all can be
run from one driver program, do you have a universal (or at least multi-language) compiler? I don't know how much that applies to LLVM's front-ends, but for gcc you can run "gcc" with C, C++, Ada, Fortran, and depending on the version, Go, Rust, D, Java, Cobol, and Algol.

Still, I am not claiming that the LLVM project, even with all its front
ends collected together, is a "universal compiler". I am merely saying
it is an example of a software system that can compile a lot of
different languages for a lot of different targets.

Sometimes even the same language has different front
ends on different OSes.

Yes. He is not lacking in ambition!
